Applications
M-Loggers are used to monitor Slope Indicator MEMS sensors. They are also compatible with EL-SC sensors.
Simple to use and economical to deploy, M-Loggers can be placed close to sensors, enhancing reliability and keeping cable costs down.
M-Loggers can push data directly to the web, where monitoring software can process the data and distribute the results quickly. Typical applications include:
  • Top-of-hole monitoring of in-place inclinometer sensors.
  • Local monitoring of beam sensors and track sensors.
  • Monitoring in areas where heavy traffic or electrical noise make short signal cables necessary.
  • Monitoring sensors that are too far apart to connect to a centralized data acquisition system.

 

Logger Components
M-Logger:
Each M-Logger can monitor up to 16 sensors.

Power Supply:
The M-Logger is normally powered by a 12V battery.
Long-term deployment or wireless communications require a charging regulator for the battery and a power source such as an AC adaptor or a solar panel.

Multiplexer:
Serial sensors eliminate the need for a multiplexer. However, a multiplexer is required to connect multiple, non-serial sensors.

Weatherproof Enclosure:
Small and medium size enclosures are available. The small enclosure is suitable for a system monitoring a single
sensor or a chain of serial sensors. The medium enclosure is required if a multiplexer is used.

Communications:
GSM modems and spread-spectrum radios will be available Q1, 2010.
The M-Logger has a special port for the GSM modem and can FTP data directly to an internet address at scheduled intervals. Spread-spectrum radios can provide a wireless, line-of-sight link between a PC and the M-Logger. Manager software is then used to retrieve data from the logger.

 

Advantages
Simple Setup:
M-Loggers are very easy to configure. The user enters a list of sensors, sets a start time, and specifies a logging interval. After that, the logger is ready for work.

Reduced Costs:
M-Loggers are a cost-effective alternative to centralized data acquisition systems. They can be affordably deployed close to the sensors, enhancing reliability and reducing costs by eliminating the long, expensive, and vulnerable runs of signal cable required with centralized logging systems.

Direct to Web:
M-Loggers can push data directly to the internet via cell modems. This simplifies data collection and speeds the the flow of data to web-based monitoring software, such as Atlas.

Wired or Wireless:
When direct-toweb efficiency is not required, data can be retrieved by a PC connected directly to the logger or connected wirelessly by line-of-sight radios.

Spreadsheet Friendly:
CSV files from the logger are ready for import, with dates and numbers formatted to the regional settings in Windows. Automation-Ready: Data formats for automatic processing include the Campbell Scientific table format and the Slope Indicator ID format.

Engineering Units:
Manager software outputs data in engineering units as well as raw data.

Switched 12V output for serial sensors or multiplexer.

Environmental:
Temperature rated for -20 to +50 °C. Logger normally housed in an enclosure.
Dimensions: 120 x 80 x 40 mm. (4.7 x 3 x 1.6").

 

M-LOGGER MANAGER
M-Logger Manager . . . . . . . . . . . Download 
Function:
Used to configure the logger. Can also display real-time readings and retrieve data.

System Requirements:
Runs on Windows XP, Vista, and Windows 7. Communicates with logger via an RS-232 serial connection. If PC has
only USB ports, a USB-serial adaptor is required.

Settings:
Logger ID, real-time clock, memory mode, sensor list, multiplexing mode, logging schedule, and communications parameters.

Real-Time Readings:
The Manager program can display real-time readings of sensors when PC is connected to the logger.

Data Retrieval:
Works with interface cable or line-of-sight radio. Retrieves new or all readings. Can clear data from logger memory.

File Formats:
CSV, Campbell Scientific, and Slope ID. CSV uses Windows regional settings for date, time, and numbers and is suitable for spreadsheets. The Campbell Scientific format and Slope ID formats are useful for automation and monitoring software, such as Atlas.
